SQL data source or LINQ

Hi All,
     For my new tool am developing I would like to know if using Sql datasource for calling stored procedures is a good option or using LINQ with creating data classes and business classes etc. is ideal ?
I would have about 20-30 fields of data I will have in my web page.
Please suggest .. (Please help if am missing on any new tools that I can use and which am missing out on with asp.net and sql ?)
